71% | Synthesis of Cyclopropane-1,1-dicarboxylic acid methyl ester KOH (42 mg, 0.75 mmol) was added to a solution cyclopropane-1,1-dicarboxylic acid dimethyl ester (100 mg, 0.63 mmol) in methanol. The resulting mixture was stirred for 4 hours at ambient temperature then concentrated. The residue was diluted with water, acidified with conc. HCl and the product was extracted with dichloromethane. The organic layer was dried over sodium sulfate and concentrated under reduced pressure to afford 65 mg (71%) of cyclopropane-1,1-dicarboxylic acid methyl ester. | |
60% | Preparation 201 -Methoxycarbon lcyclopropanecarboxylic acidDimethyl cyclopropane- 1, 1-dicarboxylate (26.08 mL, 189.87 mmol) is dissolved in methanol (319 mL) and the solution is cooled to 0 C. I NaOH (190 mL, 190 mmol, 1 eq) in water is added dropwise. The resulting mixture is stirred at RT overnight. The solution is concentrated under reduced pressure to remove the methanol and the resulting aqueous solution is washed with dichloromethane (3 x 50 mL) and acidified with 1 N HC1 (pH = 2-3). The solution is then extracted with ethyl acetate (5 x 100 mL) and dichloromethane (3 x 50 mL). The combined organic portions are dried over MgS04, filtered, and concentrated to afford the title compound (16.4 g, 60%). ¾ NMR(400 MHz, CDC13); delta 1.9-1.7 (m, 4H), 3.78 (s, 3H). | |
1,1-Cyclopropanedicarboxylic acid dimethyl ester (25 g) was dissolved in methanol (250 mL). The solution was cooled under ice cooling, and 1N aqueous sodium hydroxide (158 mL) was added dropwise thereto. The thus-obtained mixture was brought back to room temperature, and was stirred overnight. Methanol was distilled away, and the residue was washed with chloroform. The aqueous layer was cooled under ice cooling, and concentrated aqueous HCl was added thereto, to thereby adjust to pH 2. The resultant mixture was extracted with ethyl acetate, and the extract was dried over sodium sulfate anhydrate. The solvent was distilled away under reduced pressure, to thereby give the title compound (16.8 g).1H-NMR(CDCl3) delta:1.76-1.80(2H, m), 1.82-1.88(2H, m), 3.79(3H, s), 12.73(1H, br). |
With sodium hydroxide; In methanol; | REFERENTIAL EXAMPLE 161 1-(Methoxycarbonyl)cyclopropanecarboxylic acid: Dimethyl 1,1-cyclopropanecarboxylate (25 g) was dissloved in methanol (250 ml), and the solution was cooled with ice. A 1N aqueous solution of sodium hydroxide (158 ml) was then added dropwise, and the resultant mixture was warmed to room temperature and stirred overnight. After methanol was distilled off, the residue was washed with chloroform, and a water layer was cooled with ice, adjusted to pH 2 with concentrated hydrochloric acid and extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to obtain the title compound (16.8 g). 1H-NMR (CDCl3) delta: 1.76-1.80(2H,m), 1.82-1.88(2H,m), 3.79(3H,s), 12.73(1H,br). | |
Method C; <strong>[6914-71-2]Dimethyl 1,1-cyclopropanedicarboxylate</strong> (5 ml) was mixed with NaOH (1.4 g) in MeOH (40 ml)/water (4 ml). The reaction mixture was stirred at RT overnight and the solvent was evaporated. To the residue was added ether (50 ml), water (50 ml) and extracted once. The aqueous layer was acidified with 6N HCl and extracted three times with ether, the combined organic layer was washed with brine, dried and evaporated to give 1-(methoxycarbonyl)cyclopropanecarboxylic acid (4 g). | ||

1.58 g | With water; sodium hydroxide; In methanol; at 20℃; for 23h; | (1) To a solution of dimethyl 1,1-cyclohexanedicarboxylate (2.08 g) in methanol (15 mL) was added a 1Naqueous sodium hydroxide solution (13.2 mL), and the mixture was stirred at room temperature for 23 hours. Themethanol was distilled off under reduced pressure, and the residue was washed with n-hexane. To an aqueous layerwas added 1N hydrochloric acid (10 mL), and the mixture was extracted with chloroform. The extract was washed withsaturated brine, and dried over anhydrous magnesium sulfate. After drying, concentration under reduced pressureprovided Compound 2 (1.58 g) as a colorless oil. |
With water; lithium hydroxide; In methanol; at 20℃; for 1h; | Dimethyl cyclopropane dicarboxylate (10.12 g, 63.99 mmol) was dissolved in 100 mL (1:1 V:V) CH3OH/H2O and stirred at room temperature. Lithium hydroxide (2.68 g, 63.99 mmol) dissolved in 20 ml H2O was slowly added to the above solution for three times at room temperature, and then the mixture was allowed to react for 1 h with stirring. After the reaction was completed, the resultant was adjusted to pH3 with dilute hydrochloric acid, extracted with DCM, and dried over anhydrous sodium sulfate. The product without purification was to be used in the next step. | |
